ROBERT J. SEATOR, OF BATTLE CREl IHERBER'I MATTHEVTS, 0.x:

MOTOR For. nneuna'rous.

Application filed May 17,

I! '0 all whom it may concern.

Be it known that I, ROB RT J. SnA'roR, a citizen of the United States, residing at Battle Creek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Motors for Regulators, of which ,the following is a specification.

This invention relates to improvements in motors for regulators.

My improved motor is especially designed by me for regulating furnaces and I have shown the same in an. embodiment adapted for that purpose. My improvements are,

however, desirable for use and may be readily embodied 1n structures designed "for other uses.

\Iy present improvements are an adaptation of and in some respects an improvement upon the structure shown in my Letter Patent No. 1,329,553, issued l ebruary 3, 1920.

The main objects ct this invention are:

First, to provide an improved motor for regulators which is very positive in its action. v Second, to provide an improved motor actuated by Weight and hydraulic power which is simple and economical in structure and durable and not likely to get out of repair.

structural details willdeliniteh appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and means described in the following specification. The invention is dearly defined and pointed out in the claims.

A. structure which is a preferred embodiment of my inventiouis clearly illustrated in the accompanying drawing forming a part of this specification in which:

Figure I is a diagrammatic view. of astructurc embodying the features of my invention illustrated in operative relt to a furnace, the parts being shovvn manrlv ir conventional form and Without regard to proportion. o

In the drawing similar reference characters refer to similar parts throughout the several views, and thesectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring the drawing, 1 preferably mount the parts upon a base plate 1 adapted to be mortified upon a Wall or othersupport in proper relation to the furnace dampers or other ts to be controlled. In Fig. l, 2 th d attdamper of a furnace 3,

d or damper of a furnace ears of the cables 6 and 7 pulleys 8.

. V, with the locking dog released or These dampers are connected under 9 is mounted'on the while the outlet is controlled by the valve 16. These valves are of the plunger type and are oppositely disposed to coact with conical supporting bearing seats 17 and 18 respectively. The valves are provided with stein-like portions 19 and 20 which engage when the exhaust valve is closed to lift the inlet valve from its seat. The means for controlling the valves will be disclosed as the description proceeds.

The plunger rod 21 reciprocates through a 22 on the base plate. The actuating rod 23 is mounted for reciprocating movement in bearings 24 and 25 on the base plate. The actuating rod is provided with steps 26 and 2'? which limit its stroke. The actuating springs 28 are mounted on the rod to be engaged by the tappet or arm 29 on the plunger rod so that the springs are placed under compression toward the ends of the stroke of the plunger and power stored to act ate the red when it released.

The rod is adapted to engage the blade spring 39 on the valve lever 31 which is pivoted at 31 to engage the exhaust valve 16 as shown in VIII. When in the position shown in Fig. Til, the lever is actuated to close the exhaust valve and open the inlet valve. Gravity tends to open the exhaust valve and close the inlet valve as does also the water pressure so that when the actuating rod is returned to the position shown i Figs. TV and VIII, the exhaust valve opens and the inlet valve closes.

A drip cup 32 is positioned below the discharge passage 14, a drain pipe 32 being connected to the drip cup. A vent and drain pipe 33 is connected to the inner end of the cylinder 10 and delivers to the drip cup 32. This pipe 33 takes care of any water that may pass the plunger and provides a vent for the inner end of the cylinder.

The actuating rod is controlled by the locking dog or member 3a which 18 slidably mounted on the end or" the base plate to coact with notch-like keepers 35 in the rodsee Fig. Vll. A spring 36 urges the looking member to its engaging position; This locking member 34 is released by means of the trip 3?" on the plunger and the trip 38 pivoted on the base plate at 39 and controlled by the armature 40 of the electroniagnet e1.

As the details of the electromagnet form no part of the invention they are not illustrated or described herein.

The arinature' lO is provided with a notch are adapted to receive the end of the trip lever 38. When the trip lever is released by the armature and actuated to the position shown in ig. Til, the locking member is disengaged and the actuating rod is actuated by the right hand spring 28 to the position shown in Fi Ill, in which position the exhaust valve is closed and the inlet valve opened.

The water flowing into the cylinder actuates the plunger against the pull or" the weight 44 which is connected by the cable d5 to a post 4L6 on the base, the cable passing over the pulley a? on the plunger rod.

The tappet or arm 29 engages the actuating spring 28 at the left placin the same under stress or compression so that when the trip arm 37 on the plunger rod releases the locking dog 3d, the actuating rod is actuated to release the exhaust valve allowing the inlet valve to close and the cylinder to exhaust.

The return weight would at once return the plunger to its initial position were it not engaged by the detent e8 which is pivoted at 49 on the trip lever 38 to engage the keeper 50 on the plunger rod-see Fig. TIL- so that the plunger is held in its extended position until the armature i0 is again actuated when the p of the weight is sutfi-cient to release the detent, the ooacting faces of the detent and keeper being slightly inclined as shown in Fig. TX.

As the plunger moves to its initial position, it engages the lever 51 which is pivoted at 52 on the trip lever raising the same to the position shown in Fig. i and apply ing stress to the bowed spring 53 one end of which engages a lug 5% on the lever 51 and the other engages a corresponding lug 56 on the detent 48. With this spring under stress, when the armature is again actuated l to release the trip lever, it is thrown up by the action of the spring on the lever 51 to the position shown in Fig. TH and this actuates the locking member 3% to release the actuating rod so that it is actuated by the right hand spring 28 to close the exhaust valve and open the inlet valve as described.

When the plunger is again moved to its extended or actuated position the trip lever drops down as shown in Fig. TV so that it is re'e'gaged by the armature and the detent 43 engages and holds the plunger in its ex tended position.

For convenience in making the electrical conneztions. l mount an insulated plate 57 on the base plate 1. The plate 57 is provided with binding posts 58 to which the temperature control. device 59, shown conventionally in Fig. X1 is connected. The binding post 60 is connected to the source of current as the battery 61. The binding posts 58 are connected to the spring contacts 62 mounted on the plate 57 so as to be engaged by the tappot 29 on the plunger rod when the plunger rod is at the ends oi its stroke, the circuit being broken during the stroke of the plunger. L

A third contact 63 is provided to enact with the stop 27 on the actuating rod. This contact 63 is connected to the electromagnet by the connection 64., the electromagnet being also connected to the binding post by the connection which binding post also is connected to the battery by the connection 66. The connection for the binding post 58 to the right hand magnet is through the contacts 62 and 63, the parts engaging with the contacts when in the position shown in Fig. II, the connections being brokenwhenthe parts are in the position shown in Fig. III so that should they remain in this position through lack of water pressure to actuate the plunger, the battery is not run down.

lVith the parts arranged as illustrated and described, the operation of the device is as follows:

Assuming the parts to be in the position shown in Fig. II, upon the actuation of the armature ID, the trip lever 38 is thrown upwardly to the position shown in Fig. III by the lever 51 actuated by the spring 53. This movement of the trip lever releases the locking dog Set of the actuating rod 23. The actuating rod being released, its actuating spring 28 at the right hand end being under compression as shown in Fig. II, moves the actuating rod toward the right and closes the exhaust valve and opens the inlet valve, and the water flowing into the cylinder, actuates the plunger.

When the plunger passes from beneath the lever 51, the trip lever drops down and is reengaged by the armature and the actuating rod locking dog is released engaging the outer keeper of the actuating rod and holding it in its actuated position until the plunger has placed the lett hand actuating spring 28 under stress. Its trip 37 releases the locking dog allowing the actuating rod to release the valve lever, opening the drain or exhaust valve and closing the inlet valve. The plunger is retained in its actuated position by the detent 48 on the trip lever until the trip lever is again released by the actuation or" the armature from the thermostat or temperature control means, when the weight returns the plunger to the position shown in Fig. II, which completes the cycle of movement.

My improved regulator is entirely automatic, that is, there is no weight or motor to wind. It may be very. easily installed even by an unskilled workman, as the parts are all assembled upon the base plate which may be mounted on any suitable support and connections made to the dampers to be operated.

I have not attemptedto illustrate or describe certain modifications in structural details which I contemplate as I believe the disclosure made will enable those skilled in the artto which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention,
